Product image: example of an electric heating panel. The photograph is not evidence of cleanroom suitability; this requires a separate assessment of the exact appliance and application.
An infrared panel in a cleanroom can only be considered within the design and qualification of that specific room. A smooth surface or the absence of a fan does not establish that an appliance is suitable for a particular cleanroom class.
What does a cleanroom classification tell you?
ISO 14644-1 describes air cleanliness classification based on concentrations of airborne particles. This is a property of the assessed room under specified conditions. A standalone heating panel does not automatically make a room comply with that classification.
ISO 14644-14:2026 addresses equipment assessment in relation to airborne particles. It does not assess biocontamination, cleanability or resistance to decontamination agents and techniques. Have the chosen appliance, positioning and use assessed against the process requirements and quality plan.
Radiant heat does not eliminate thermal air movement
A panel can emit radiant heat without a built-in fan. However, its warm surface can also cause convection. Positioning can therefore affect air movement and temperature distribution.
Desired airflow, pressure relationships and particle control remain functions of the complete room design. Have changes checked by the responsible cleanroom specialist and include them in the necessary measurements and qualification.
Assess cleaning and material compatibility
For the exact version, ask about materials, seams, fixings and access for cleaning. The manufacturer must specify permitted agents, concentrations and methods. A general coating description does not establish resistance to hydrogen peroxide vapour or other decontamination processes.
An IP classification describes protection against ingress of substances or water according to the relevant classification. It does not establish sterilisability, chemical resistance or cleanroom suitability. Choose the version based on the actual cleaning protocol.
Include process and electrical safety
Assess surface temperature, permitted clearances, electrical connection and effects on measuring equipment. Maintenance and replacement procedures may also form part of the quality plan. A general EMC statement does not guarantee trouble-free operation in every combination with sensitive equipment.
An explosive atmosphere requires a separate assessment. The applicable zone, dust or gas group and temperature conditions determine which equipment may be suitable. A standard heating panel must not be installed there without appropriate supporting evidence.
What information is needed for a proposal?
- Room class, process and required operating state.
- Floor plan, air supply, extraction and critical work areas.
- Heat demand and permitted temperature variations.
- Cleaning agents and any decontamination processes.
- Required material declarations, test data and qualification steps.
We can help gather information about a proposed product. The responsible designer and quality organisation determine whether it can be used within the validated system.
Discuss your application with us
We supply private and business end users as well as dealers, installers and wholesalers. Tell us about the room, its use and any product codes. We help coordinate version, positioning and controls with your situation.
